Abstract

본 발명은 이색성(optical two color effect)물질 제조방법에 관한 것으로 종래의 이색성 물질의 제조방법으로서는 금속산화물의 다층진공증착법, 염료염착법이 알려져 있으나 이러한 종래의 제조방법은 제조비용이 과다히 소요되거나 내약품성이 약한 결점이 있었던바, 본 발명은 천연 운모의 미세 입자 표면에 굴절율이 높은 금속산화물을 일정 두께로 피복함에 따라 진주 조개 껍질에서 볼 수 있는 무지개색과 같은 특유의 간섭색이 나타나는 금속 산화물층위에 다시 구리, 니켈등의 무전해 도금에 의한 금속 미립자를 피복하고 프탈로니트릴을 반응시켜 금속-프탈로시아닌층을 형성시키는 것으로 이러한 이색성 운모는 정면에서 보면 청녹색으로 보이며 측면에서 보면 금속산화물에 의한 간섭색이 보이는 시변각 이색효과를 가지며 본 방법에 의한 이색성 물질은 경제성이 있고 내약품성이 양호하며 도료, 잉크등에 사용시 시각 변환에 의한 색상 변화 효과를 줄 수 있는 것임.The present invention relates to a method for manufacturing an optical two color effect material. As a conventional method for manufacturing a dichroic material, a multilayer vacuum deposition method and a dye dyeing method of a metal oxide are known, but such a conventional manufacturing method is excessively expensive. The present invention has a drawback of weakness or weak chemical resistance. The present invention provides a metal oxide having a specific interference color such as rainbow color found in a pearl clam shell by coating a metal oxide having a high refractive index on the surface of fine particles of natural mica. On the layer, metal fine particles are coated by electroless plating such as copper and nickel, and phthalonitrile is reacted to form a metal-phthalocyanine layer. The dichroic mica appears blue green from the front and metal oxide from the side. Dichroism by this method The material is economical and has good chemical resistance, and when used in paints and inks, it can change the color by visual transformation.
